Description of problem:
If you pipe the output of guestfish to a file, then the
output includes the progress bar.
Probably we should send the progress bar output directly
to /dev/tty, or maybe to stderr.
Version-Release number of selected component (if applicable):
guestfish 1.19.43.
Steps to Reproduce:
1. inspect-list-applications <root> | cat > applications
Actual results:
The output may include the progress bar.
